CHECK-.HOOK i-:w/iz.V

SPECIFICATION forming part of Letters Patent No. 515,798, dated March 6, 1894.

Application filed September 30, 1893. Serial No. 486,910- (No model.)

To all whom t may concern): y

Beitknown thatLCnAnLns HENRYSHULTZ,

` a citizen of lthe United States, residing at Val* removably engaging the hook and designed to be applied to the rear end of the overdrawstrap; to construct the eye of spring-wire and to adapt it when connected with the hook to be secure and not liable to become displaced through accidents.

With these and other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawingsz-Figure l is a perspective view of a check-hook, a ,portion of an overdraw strap, and an eye or coupler engaging the hook and'secured to the strap land constructed in accordance with my invention. Fig. 2 is a detail in plan of the preferred form of eye or coupler. Fig. 3 is a longitudinal sectional view of the same. Fig. 4 is a detail in perspective of a modified construction of eye or coupler.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing inyinvention I employ ablank of spring-wire of suitable gage and length, and by proper means coil the same at each side of its center, as at 1, whereby I produce an intermediate cross-bar 2 designed to be connect ed with the rear end of a side check-strap 3. By bending the blank as described It'orm opposite terminals 4 which are disposed inwardly to a common point in rear of the bar 2 and interlock, forming an intermediate check-hook engaging eye 5. These terminals are then bent upon themselves in an obtuse manner so as to form loops 6 at each side of the eye, after which they are linwardly bent and forwardly dispsed, producing the engaging ends 7 which terminate in hooks 8 that are engaged over the rear sides of the coil 1. It will be seen that in order to engage the eye 5 of the coupler with the checkbook it is sim ply necessary to compress the two spring-members formed by the terminals 4, the loops 6, and the arms 7, so that the loops 6 are nearly brought into alignment with each other, thus enlarging the eye 5 and enabling the operator to pass the same readily over the end of the check-hook. When passed over the end of the check-hook and bolted to its position the spring-members are released, and the tendency being to separate causes the opposite sides of the eye 5 to engage snugly with the aforesaid hook and obviate any accidental displacement. Desired disengagement may be readily accomplished by simply compressing .the two members in the manner before described, and slipping the couplingldevice up over the end of the hook. g

I have illustrated a modified construction or form of coupler, which, while embodying the principles of the one previously described, has its details slightly altered. In this'modified construction I employ a blank of springwire in the same manner as before,but in lieu. of ceiling the same at opposite sides of the center form the coil 10 directly at the center. The terminals 11 are, as in the previous instance, converged rearward to a common point where they are interlocked, forming the checkhook engaging eye 12, are then diverged or vbent obtusely in opposite directions forming the loop 13, and finally the forwardly disposed engaging-arms 14 which terminate in hooks 15, which en gage the front portions of the coil 10. The overdraw-strap is connected to the eye 10 in lieu of the bar 2, as in the side checkstrap hook. The operation is precisely the same as before described, in that the tendency of the coil 10 is to separate the springmembers, thus decreasing the size of the eye l2 and causing it to bind upon the cheek-hook. This binding may be relieved, however, by a compression of the members whereby the loops 13 are swung more nearlyinto alignment with each other.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a veryV simple.

coupling-device designedto be readily applied to the rear end of the overdraw-strap in harness, and when so applied will form an eiective coupler for the same with the check-hook,

IBO

the coupling operation as Well as the unconpling operation being readily carried on by a simple compression of the two spring-members so as to align the loops, thus enlarging the eyes 5 or 12 so as to readily receive orbe disengagedfrom the check-hook.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. The herein described hook made of wire coiled at one end, having the opposite terminals extended outward but disposed inwardly so as to cross each other at a predetermined point, then formed into loops which areinterlocked, then extended back to the starting point and having the ends of the terminals engaging with the coil, thereby forming two looped interlocking members, each of which is composed of two bars, the bars of each member crossing one another, and the inner bar of both members likewise crossing and interlocking, substantially as specified.

2. The herein described check-hook coupler, the same formed of spring-wire blankbent to form coils at its front end,and having its opposite terminals rearwardly disposed and` at 7 and terminating in hooks 8 engaging thel coils l, substantially as specified.

In testimony that I claim the foregoing as myown I have hereto affixed my signaturein the presence of two witnesses.

CHARLES HENRY SHULTZ.
